> **Note:** Custom slash commands have been merged into skills. Files in `.claude/commands/` still work, but skills (`.claude/skills/`) are recommended as they support additional features like supporting files, invocation control, and subagent execution.
- **[Skills](https://code.claude.com/docs/en/skills)** - Reusable knowledge, workflows, and slash commands that Claude can load on-demand or you invoke with `/skill-name`
-- **[Subagents](https://code.claude.com/docs/en/sub-agents)** - Isolated execution contexts that run their own loops and return summarized results
+- **[Agents](https://code.claude.com/docs/en/sub-agents)** - Custom agents in `.claude/agents/` with their own name, color, tools, permissions, and model — usable as default main agent (`"agent"` in settings.json) or as isolated subagents via the Task tool
- **[Memory](https://code.claude.com/docs/en/memory)** - Persistent context via CLAUDE.md files and `@path` imports that Claude sees every session
- **[Rules](https://code.claude.com/docs/en/memory#modular-rules-with-clauderules)** - Modular topic-specific instructions in `.claude/rules/*.md` with optional path-scoping via frontmatter
- **[Hooks](https://code.claude.com/docs/en/hooks)** - Deterministic scripts that run outside the agentic loop on specific events
- **[MCP Servers](https://code.claude.com/docs/en/mcp)** - Model Context Protocol connections to external tools, databases, and APIs
- **[Plugins](https://code.claude.com/docs/en/plugins)** - Distributable packages that bundle skills, subagents, hooks, and MCP servers
